Title: Improvements in chucks for machine tools
IPC: B23B31/175
Filed: 1957-01-28
Abstract: 848,551. Chucks. PRECISION INDUSTRIELLE. Jan. 28, 1957 [Dec. 3, 1956], No. 3039/57. Class 83 (3). A chuck 3 for work 4 centred by other means, e.g. centres 5; 6, comprises' radially movable jaws M operated by a draw-tube 20, through means which allows the jaws to move through different individual distances in order to ensure that they apply equal gripping pressures. An odd number of carriers 11, to which the jaws are fixed by screws 10, are moved radially by levers 12, on pivots 13 and connected to the draw-tube 20 by a housing 19a, 19b. A spherical roller 16 on the lever is received in the groove of a swivelling member or (as shown), between rings 18a, 18b having spherical outer surfaces engaging spherical seatings in the housing, which is guided by a tube 3a fixed to the front of the chuck. Upon operation of the draw-tube to close the jaws on to the work, the outer surface of which is not concentric with the axis of the centres 5, 6, supporting the work, the first jaw to engage the work, and thus arrest pivotal movement of its lever 12, causes the rings 18a, 18b to swivel in the sliding housing, the swivelling movement continuing until the other jaws contact the work and end the pivotal movement of the other levers 12. To prevent bending of the work due to the jaws not engaging the work simultaneously, plungers 21, opposite the jaws in the three-jaw construction illustrated, engage and support the work before it is engaged by the jaws. The plungers are operated by projections 28, on the housing 19, which engage and move sleeves 26. The movement is transmitted, through a spring 29, to a piston rod 25 and a piston 24 having an annular groove 32 in communication with the space 22a behind the plunger 21, through passages 30, 31, and with the space 35 ahead of the piston, through a port 34 in the piston and an annular groove 33 in the sleeve 26. The spaces 35 are interconnected by passages 31, 36, to balance the forces applied by the plungers, and movement of the pistons expels liquid from the spaces 35 to the spaces 22a, through the grooves and passages 30 ... 34, thus closing the plungers 21 on to the work. The application force of the plungers increases until the spaces 22a are sealed by closure of the ports 34 upon compression of the springs 29. Instead of closing the passage 31 by a plate 40, it may be closed by the end of the machine spindle. In a modification (not shown), a single piston 24 may force liquid behind all of the plungers 21. Lathes. The live centre 5 is located in the hollow spindle 2a or, for longer work, in a tubular extension of the spindle extending out of the headstock 2. Reference has been directed by the Comptroller to Specification 824,016.

Patent GB-469905-A (GB)
Title: Process for spinning endless threads of viscose
IPC: D01F2/06
Filed: 1936-02-05
Abstract: <PICT:0469905/IV/1> Endless threads of woolly character are obtained by extruding viscose into a coagulating bath, passing the cellulose xanthate threads to a take-up device, and then conducting them in a continuous manner and free from tension through a bath or baths which is heated above 70 DEG  C., and which, effects decomposition of the cellulose xanthate, the threads remaining in the bath or baths so long that decomposition to cellulose hydrate is completed by the high temperature.  The hot bath may comprise an organic liquid or a salt solution.  Preferably, the xanthate filaments are drawn from the precipitating bath by squeezing rollers, or a godet and are then passed into the decomposing bath free from tension.  The foaming effect of the decomposing bath disturbs the parallel formation of the filaments and produces strong crimping.  The viscose used may have a high alkali content and may contain pigments, matting agents, and other additions.  In an example, ripened viscose is spun into a solution of sodium and ammonium sulphates.  The bundle of filaments produced is drawn from the bath by a roller and allowed to fall into a channel containing glycerine at 130 DEG  C.  The hot glycerine carries the filaments to the end of the channel and on to an endless sieve band.  The filaments are then sprayed with water and other liquids.  Instead of glycerine a poly-glycol may be used for the conversion bath. Several parallel loose bands of filaments may be treated on the endless band.  As shown, filaments b of cellulose xanthate issue from nozzle a and are drawn through squeeze rolls c from which they drop into trough d.  Heated liquid passes through the trough and carries the filaments on to a sieve band f.  The liquid is collected in trough h and returned through a pump, storage vessel, and heater, to the trough d.  Treatment liquids are applied to the regenerated cellulose filaments by the sprays e.

[Class 2 (iii)] Resinous products having high electric resistance and low power factor and dielectric constant are obtained by the interaction of halogen substituted aromatic hydrocarbons with aldehydes in the presence of strong acids as catalysts and in the absence of water. The product may be incorporated with polymerized vinyl compounds e.g. polystyrene, polyvinyl acetal or acetate. Catalysts specified comprise sulphuric, phosphoric and organic sulphonic acids having a Ph of at least 4, the catalyst being employed in amounts less than 1/10 mol. per mol. halogenated compounds or less than 6 per cent. on the combined weight of halogen substituted compounds and the aldehyde. Halogenated aromatic compounds specified comprise mono halogenated naphthalene, diphenyl, benzene, toluene, phenanthrene, anthracene, fluoranthene, hydrindene, pyrene, chrysene. Aldehydes specified comprise formaldehyde, paraform, paraldehyde, acetaldehyde, acrolein, crotonic aldehyde, benzaldehyde and may be used in solid, liquid or vapour form. The reaction is carried out at temperatures e.g. 140-250‹C. at which the water formed in the reaction is immediately distilled off and may be raised in the final stage to cause combination of the catalysts, sulphuric acid with excess of the chlorinated compounds to form a sulphone; alternatively excess of catalyst may be removed by addition of calcium oxide. Plasticizers-triphenyl phosphate, di-butyl phthalate ; fillers-asbestos, diatomaceous earth, bentonite, clay, metallic oxides, silica, silicates ; lubricants-calcium stearate, paraffin wax, blown oils, stearic acid, carnauba wax, ceresin-may be added. When 'used as an impregnating agent the resin may be dissolved in aromatic hydrocarbons e.g. benzene, toluene, xylene, naphtha or ketones e.g. acetone, methyl ethyl ketone. In examples (1) 100 parts monochloro naphthalene and 4 parts benzene, sulphonic acid are heated to 140-250‹C. under refluxing conditions and 20 parts paraform added with stirring the reaction being carried on until paraform collects in the condenser. The temperature is then raised to 270‹C. Impurities are removed by steam distillation and a brittle resin melting at 88-110‹C. is obtained ; (2) parachlorodiphenyl is heated similarly with sulphuric acid while passing in formaldehyde gas ; (3) a chloronaphthalene resin formed according to the invention is mixed with tricresyl phosphate, and polystyrene. The Specification as open to inspection under Sect. 91 referred to included the treatment of halogenated substituted phenyl ethers or sulphones and included the use of ketones as alternative to aldehydes. This subject-matter does not appear in the Specification as accepted.

Title: Method for continuous production of sulphur and ferric oxide from ferrous sulphide
Inventor: AARVIK JOHN
IPC: C01B17/06
Filed: 1953-02-09
Abstract: Elemental sulphur and ferric oxide are obtained from ferrous sulphide by treating the sulphide in the fluidized state in a first zone of a furnace with a mixture of sulphur dioxide and oxygen to yield ferroso ferric oxide, sulphur and sulphur dioxide. The sulphur is removed and the sulphur dioxide <PICT:0726216/III/1> replenished with technical oxygen is recycled to a second zone of the furnace to fluidize and oxidize the ferrosoferric oxide fed thereto, the gases then being passed to the first zone and the ferric oxide formed, withdrawn.  The amount of oxygen employed is such as to maintain constant the quantity of sulphur dioxide circulating, this quantity being from 3 to 20 times the quantity formed by the reaction of the oxygen and ferrous sulphide. Reaction temperatures should be above 780 DEG C. preferably 900-1000 DEG C., avoiding sintering.  The oxygen fed normally contains 3-5 per cent. of nitrogen and this nitrogen may be allowed to accumulate in the circulating gas until the latter contains 20-30 per cent. nitrogen, after which it is separated by condensation and fractionation.  As shown in the figure, ferrous sulphide is fed by pipe 1 to a reaction zone A where it is fluidized by a mixture of oxygen and sulphur dioxide from reaction zone B below. The mixture of sulphur dioxide, inert gases and elemental sulphur leave at 3 and pass through a dust cleaning unit C and a sulphur condenser D.  The residual gases pass through a dust separator E, a separator for inert gases F and a heat exchanger H, after which the sulphur dioxide is enriched with oxygen and recycled to the lower reaction zone B.  This zone is fed with ferrosoferric oxide formed in zone A and overflowing therefrom by pipe 2.  This oxide is oxidized to ferric oxide in zone B and discharged at 5.
